Carrying out engineering surveys – geological and hydrogeological in the territory of the new substation "Pomośrie"

Carrying out engineering surveys by performing core drilling, including continuous penetration testing. As indicated by the designers tasked with preparing the investment project for the construction of a new substation, the testing should include 5 core boreholes and 5 continuous penetration tests, with a minimum depth/length of 10 meters, in the territory designated for the new substation, at locations suitable and agreed with the contracting authority, taking samples for laboratory research of lithological varieties and groundwater found during the drilling. The specified drilling depth of 10 meters is the minimum and is performed unconditionally. If, during the course of the surveys, the contractor determines that the depth of the work needs to be increased to obtain reliable results/indicators, they should notify the contracting authority in the manner provided for in the contract. It is necessary to reach solid ground and penetrate it by at least 1 m. Performing additional exploratory boreholes beyond those specified, as well as increasing the drilling depth/penetration length without the permission of the contracting authority, will not be paid for. The report from the completed engineering surveys will be used by the contracting authority as initial data (pre-project surveys) when preparing the investment project for design. In addition to the specified surveys, the order also includes the exercise of author's supervision during construction.
